EJSONPARSE error with npm when trying to install a package

Question

When I try to install an npm package after running npm init, I am am met with this response.

C:\Users\User\My Documents\brackets\2007webpackes6>npm install --save-dev babel-core
npm WARN package.json 2007webpackes6@1.0.0 No description

The error report is telling that there is no data in the "package.json" but it's there when I open the file.

Package.json:

{
  "name": "2007webpackes6",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}

Any help would be much appreciated.

Answer 1

I had the same issue just today. I used the git bash. When I tried it with the windows cmd it worked just fine. Now this doesn't tell you why the error is occurring but maybe it will get it working.

Answer 2

我在尝试安装Cordova时遇到了相同的错误，请尝试“清理npm缓存”。
